The word "loph" is a little tricky to spell, as it has a silent "ph" that can confuse many people. The correct spelling is L-O-P, pronounced /lɑp/. The "ph" in this case is actually a remnant of an older spelling convention that used to indicate a "p" sound at the end of a word before the spelling reform of 1930. Nowadays, the "ph" is no longer necessary and can be a source of confusion for some.
